Hello dear forum, i follow the detailed descriptions to make a simple WebService with JDK 6 and JBoss 4.2.3 from this website: http://blog.vinodsingh.com/2008/09/jax-ws-web-service-and-jboss.html?show... When i deploy the .war to JBoss, i get the following Errors: | 17:07:14,312 INFO [TomcatDeployer] deploy, ctxPath=/HelloWorld, warUrl=.../tmp/deploy/tmp7738HelloWorld-exp.war/ | 17:07:14,781 ERROR [STDERR] 23.10.2008 17:07:14 com.sun.xml.ws.transport.http.servlet.WSServletContextListener contextInitialized | INFO: WSSERVLET12: JAX-WS context listener initializing | 17:07:16,109 ERROR [STDERR] 23.10.2008 17:07:16 com.sun.xml.ws.transport.http.servlet.WSServletDelegate <init> | INFO: WSSERVLET14: JAX-WS servlet initializing | 17:07:17,000 INFO [WSDLFilePublisher] WSDL published to: file:/C:/JavaStuff/jboss-4.2.3.GA/server/default/data/wsdl/HelloWorld.war/HelloWorldService7739.wsdl Generating some client stubs worked, but trying to invoke a client, i get the following exception: | 17:14:38,093 ERROR [[HelloWorldWebService]] Servlet.service() for servlet HelloWorldWebService threw exception | java.lang.ClassCastException: com.sun.xml.messaging.saaj.soap.ver1_1.Message1_1Impl cannot be cast to org.jboss.ws.core.soap.SOAPMessageImpl | at org.jboss.ws.core.jaxws.SOAPFaultHelperJAXWS.toSOAPMessage(SOAPFaultHelperJAXWS.java:245) I have also tried JBoss 5.0 and the JBossWS-patches to jbossws 3.0.4. I believe that there are some class-loading problems with Java 6, and filled the ${JBOSS_HOME}/lib/endorsed directory with jars mentioned on this page: http://thesmallpotato.blogspot.com/2007/06/jdk-16-jboss-420-ejb3-web-serv... ,but it did not help. I then added jboss-jaxws.jar and jboss-jaxws-ext.jar, but without success again... So i thought maybe the error comes from my web.xml, which i have a question for: | <servlet> | <servlet-name>HelloWorldWebService</servlet-name> | <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class> | <!-- servlet-class>biz.accelsis.helloworld.HelloWorldWS</servlet-class> --> | </servlet> | Can you tell me which value to put into the <servlet-class> tag? Thx in advance for all the help, i am really stucked here. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4184257#...
